The Hegemony Gods blocks the CXA from the way to the Beach through Galeem and Dharkon. Cue much of the alliance horrified at their presence.
"The Hegemonies... They're..." The SHIFTers are devastated.
"Their eyes are glitching... the same way as Tracking Error and those Titans!" Kado recognized the eyes.
"You... must die." Hajun (Sixth Heaven) spoke up mentally.
The entire alliance ends up hearing on their head and processors.
"They're telepathically calling us, because they cannot speak to us directly, 'cause we're in space." Ms. Continuum noted. "But still... they've been..."
"Corrupted. By the evolved Equation." Kado revealed.
"No... How could it be!?" Sigma Klim is shocked.
"Welcome to Anti-Life." Hirume (Seventh Heaven) called. "All is one in Anti-Life. Concede the corruption, or be annihilated."
"Ms. Yaoyorozu is threatening us!" Angela responded. "I'm gonna call everyone to watch out!"
"Haven't you embraced our salvation?" Marguerite Breuil (Fifth Heaven) is corrupted, and thus has twisted embrace.
"Oh no! Not Anti-Life again! That Anti-Life girl and her companions sure did a number to the Hegemonies!" Phi nearly left the cockpit. "I can't-"
"Oh please!" The lost trio blocked Phi.
The Battle Buses then barraged with lasers and space projectiles. It doesn't work.
"Just as durable and imposing as ever." Reiji shrugged.
Shulk... but with Omnitrix, arrived at the cockpit.
"They're overly strong! It's time to unleash the Zero omega-mech!" Said with the Omnitrix.
"Shulk, wait... Ben Tennyson?" The entire crew noticed.
"I can use Visions! And yeah, it's best to actually pilot the Zero Point altogether, just like at the end of last time!" Ben suggested.
"Oh..." Telos is surprised.
"Giving a page of Edgerunner to Asura the Destructor, and activate the Omni Super Saiyan?" Angela is weirded out. "Vajra-edge?"
"We have no other-"
Then the Mecha Fusion Overlord is pushed by Mitra Paramatman (First Heaven), craving into dozens of Battle Buses.
"Now!" Ben fled.
Telos emanates surplus of Zero Point energy to build up every power at the dome, while Angela quickly tags Asura with a page from the Edgerunner book.
"Omni Super Saiyan! Open!" Angela charged its content.
Cue Asura mutate to fuse with what was a legend. Vajra-edge is back.
"Bring us Gogetama!" Chya called through all the Buses. "And with Ultra Instinct and Ultra Ego pushing no-limiter Omni form, and fuse them with Xeno Gogeta!"
"Hmph." Ren Fuji doesn't care.
Suddenly, the fusion of Xeno Gogetama and the Vajra-edge flew right off the Battle Bus, and went straight into the Mecha's cockpit. Cue an extremely bright flash that engulfed space itself, blinding the corrupted Hegemonies.
"It's too intense!" Nerose Satanael (Third Heaven) covered his eyes.
"Fuck!" Magsarion (Second Heaven) as well. "Just what are they doing!?"
The flash receded not long after. It was the multiversal extension of Super Galaxy Gurren Lagann (超銀河グレンラガン), all the Battle Buses, the Omniversal Spirit Bomb, countless Islands from timestreams and multi-omniversal energies, all gathered together, that resembles and of the same size as Tengen Toppa Gurren Lagann, but more intense and even further, and that's just the inner body which burns intensely with enhanced Zero Point energy from its core, in rainbow tint. Then the technologies, from all kinds of mechas across the omniverse (including every single versions of Demonbane, even the Dead End), all merged into an cybernetically-enhanced exoskeleton that acts as an actual physical skeleton. The islands with Zero Point, which are rifted copies of the Island at various points and timestreams, all connected and fused to the skeleton like the tissues attached into the body, ending in morphing the exterior into wearing an armor resembling the ones from the Seven and that of the Ageless Champion and even the Cube Queen, all made of the Chrome and the leftover technology (same as the skeleton) and all those islands. The mask ended up being a gigantic combination of the Seven's visor helmet, the Ageless Champion helmet, and the Tengen Toppa sunglasses. The chest is adorned with a colossal matching replica of the Herald Tree, but with Herald wearing the sunglasses from Gurren Lagann. And finally, the same wings as Ariana Grande but enlarged accordingly. That's not all: full Omni Super Saiyan hair, red attunement anchors (representing Omni Super Saiyans) inside the materialized energy body which assumed a dark bluish-purple galactic hue. The armor made of islands takes the combined colorings of the Storm and the Zero Point-empowered Cubes on terrains, the sunglasses on Herald Tree chromed to match the logs, and that while tree is now essentially covered in Zero Point liquid. And the visor helm has the limiter mark in pure 'V' without bar, indicating the lack of Omni limiter. And the rift crystals as wings now takes form of X-shaped wings similar to Beta Spark Armor awakening.
The returning Tengen Toppa-sized mecha doing the Gunbuster pose overwhelmingly prominently. The mecha has its visor helmet displayed in rainbow marks, and adorned with the Zero Point-empowered Cubes.
Cross-trivia: Still 126 billions light years tall, same as Tengen Toppa Gurren Lagann.
"Behold! It has returned!" Telos in front of the mech, doing the exact same pose, and engulfed by energy. "Heaven Ascension Zero Point!"/"天元突破ゼロポイント!""This machine..."
A flashback of Zerobreaker's original demise struck the Hegemonies."Attack!" Telos commanded.
Everyone else except the fusion - Vajra Gogetama - teleported out, showing enforced space survivability due to... Cross All technique, empowering them again to no-limiter Omni Super Saiyan level. The alliance went zerg-rushed the Hegemonies, using the power of the mecha and Omni Super Saiyan to barrage them. Ben Tennyson and his counterparts and co. with Omnitrixes, in particular, received the Zero Point/rift energy into their respective Omnitrix, which is further boosted by the Cross All.
"It's hero time!" The Omnitrix wielders then transforms into Echo Echo at first, then massively self-duplicated, and then transformed into various notable Pantheon Denizens.The alliance was able to put up a very good, if technically destructive, fought against the Hegemonies, with the Hegemony Gods themselves struggling to handle hundreds of no-limiter Omni Super Saiyan level. Especially Goku and Vegeta as actual no-limiter Omni Super Saiyans.
Cue a call from the Zerobreaker, who just assimilated Chya (the alternate timeline one) as the new body. "I got a new- wait... What's wrong!?"
"Help us! The CXA became too strong!" Mercurius (Fourth Heaven) panicked. "That mecha... it's like... you being... erased... That mech..."
Liu Kang immediately dealt a brutal blow right to Mercurius' side. Meanwhile, the Zerobreaker is horrified at the report, being reminded of her ultimate defeat...
"We don't want to go down without a fight, and we don't intend to!" Magsarion despite in the receiving end of the omniversal-level beatdown. "Come, you traitors and co.!!!"
The alliance was beating down the corrupted Hegemonies without much effort."How did you think of that, suckers!?" Vajra Gogetama questioned.
"Teamwork! And they're powerful!" Ben told the fusion. "Miss FF, what do you have?"
Chya chuckled, and immediately opened the controlled Last Stop above the mecha, to buff everyone up.
"How!? How could the Last Stop be controlled in use at all!?" Hajun is flabbergasted. "No no no-" *get blasted*
This horrified Zerobreaker even more, and it doesn't help that Chya did Panoa's melody in space, recorded as mental sound to the gizmo. Which noticed both Oleander and the Mindsplitter.
"What!? The Last Stop can be controlled!?" Oleander checked the gizmo."No... how can it be..." The Mindsplitter immediately steps back.
"Last Stop not being erasing memories... how?" Zerobreaker immediately revulsed. "That and this mech... WHY!?"
Not long afterwards, the Hegemonies are exhausted and beaten down bloody, while the entire alliance returns to the mecha.
"No... help... us..." The Hegemonies passed out.
"We will help. No more Anti-Life corruption." Telos now co-pilot. "You'll be restored. We do not intend to kill any of you."
The gateway closes, and then the mecha covered the Hegemonies with the hands. Cue a bright flash of healing and restoring inside, pre-powered by the Life Equation.
"Anti-Life shouldn't go amok." And the mecha absorbs the Gods, bringing them all inside.
"You..." The Zerobreaker rifted to the front of the face. "You destroyed me! Now I want to destroy you!"
"Bruh!" Travis facepalmed inside his cockpit.
"What!?" The alliance is exasperated."
"Last Stop: Almighty Push!"/"最後の停留所: 神羅天征!"
Zerobreaker unleashed a gravity blast that vibrated the entire thing.
"No! Critical! It's being whacked!" Cue Vajra Gogetama receiving hurt. "Arrrghhh!!!"
"Omni, eject!" The alliance returns to their transportation.
The rifts went all over the place, tearing the entire uber-mech down. Telos immediately retreated the main Mecha all the energy and supermass, and everyone escapes with the Battle Buses and the actual mechs... as the Zero bot explodes as if succumbed.
Zerobreaker broke out a psychotic laugh, knowing that she's far more than powerful enough to finally destroy the Omni Super Saiyan of the Zero Point.
"Whew, that was close!" Carlos sweated.
"I have more power than you'll ever have... I hope you die within project..." The Zerobreaker mocked the alliance.
Cue the Battle Buses passing by, led by the Mecha and well, crashing onto the caster. She immediately sidestepped all of them, and stopped caring: she had enough power, and so will the Order.
"Hm?" Chya noticed something. "What? Look behind."
"This new body feels great. It's the best, because it's compatible with everything I had and have." The Zerobreaker then teleported back.
...but not before the Mecha capture the shape of her.
"I believe this is just one of our ultimate weapons. Thanks to it, we finally got the Hegemony Gods back." Arak reverted back. "Thanks goodness we ejected-"
"That body! It look like a five-fer!" Ma notified Chya."
"What!? Five... 5 equals 4 plus 1... 4..." Chya figured it out. "No! She has..."
"Miss, the Zerobreaker have changed her own body dozens of times throughout. So I knew it." Angela realized. "She had your body. And it and the modifications gave her greater power. If it wasn't for the ejection, we all would've been annihilated! She's a Realitier already!"
Meanwhile...
"Help! Help! Help!" The Cube Queen tried in vain.
"What's up, old queen?" M approached the QDOT machine.
"Who are you!?" The Cube Queen questioned.
"We're the ultimate Core Crystal representatives." N approached. "Be glad you're not killed immediately."
"No! What have I done to you!?" The Cube Queen slammed.
"What?! You seriously want to be free that much?!" M meanly refuted.
"She's helpless. We wait until the caster come back." N suggested.
"Help me! Someone help me!" The Cube Queen pleaded. "Help-"
"NOBODY'S HELPING YOU!" N yelled at the Cube Queen.
"Lady and gentleman, will I?" Oleander arrived with his counterpart in moody state.
"For sake of our rift." The Mindsplitter setup the sensory liquid. "Here be future, hail the Last Stop. We do this for Anti-Life Is!"
"No..." The Cube Queen then fell 'asleep', getting into the same sensory as Darya Kane used to.
The Cube Queen is brought to the Last Reality, but devoid of life.
"The Last Reality... home..." The Cube Queen recognized it. "But... why?"
Multi-colored aura surrounded her, and apparitions of various otherworlders walked around.
"The High Override conquers! All will be beneath me!"
And some cyberpsychos attacking each other for the Super Star.
"Lo and behold! The accursed-" And the Ultrom Shredder gets dusted - literally.
"What in the..." The Cube Queen is overwhelmed by the sight...
And monsters from the worlds of Kamen Rider showed up, alongside landmarks of the same worlds. And TIE fighters shooting down those flying ones. And zombies attacks the cyberpsychos and a vampire-werewolf hybrid.
"How!?" The Cube Queen is surrounded by the auras, as more and more otherworldly things get into the Last Reality.
Soon enough, the aura engulfs the fenale ruler. Then she ends up deeper into the realm.
"Huh? Where is this?" The Cube Queen had no idea.
Chya suddenly appeared, and grabbed the Cube Queen on the latter's crown.
"Who are you?" The Cube Queen asked. "I'm the ruler of the Last Reality. You are?"
"Chya. The Forgotten Four, senior memory researcher. The Lady of Convergence." Chya introduced herself. "Oh, what a coincidence. I just fell asleep again, and well... here again. You're at the realm containing the Last Stop. I have fine control over it, so the glimmer wouldn't break memories into oblivion like it normally would."
"Chya? I've never really known you at all." The Cube Queen doesn't know.
"You're from the Last Reality. Apparently, you helped the alliance from Continuim Exploitation Authority against the Zerobreaker, as an extra member of the Seven: the Queen." Chya explained. "I'm here to tell you that the Zerobreaker, the one you exiled, may have actually used your body from an alternative timeline."
"I saw the body. I saw the caster... holding her. That body..." The Cube Queen recalled.
"She with that body nearly destroyed us. Anyways, we're on our way to the Beach." Chya continued. "That body is mine! Which means she..."
"Finally got it. And here I was, thinking she's erased for good." The Cube Queen replied. "They did it. They brought her back."
"Yes, the Order of the Pariah did. I'm giving you MEM-file to let you know-" Then Chya disappeared.
Cue the Cube Queen receiving the contents of the files about the Order.
"Uh oh." Oleander noticed. "The system is in trouble! Stop the machine!"
The Mindsplitter stopped the operation for now, and the Cube Queen violently woke up.
"What? Files of the Order?" Oleander saw the MEM folder.
"Yeah... established in the Dark Multiverse. Those two..." The Cube Queen mumbled.
"Great, looks like all the leaked infos has been dumped into the mind of that alien." The Mindsplitter opened the folder. "What? She sent it?"
